I have queried 2 of the japanese drivers today. Their response was that the understeer was actually gone and that the subaru leaned more towards oversteer under boost if not handled correctly. Also they commented that they hardly engaged abs on the circuit especially when they run on semi slicks.

Also another commented that lsd is one thing, not able to enter corners correctly wil deem the lsd useless.

Will get more info from the other drivers when they respond.
